IOIL-CAKE-SACIKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 654,058, dated July 17, 1900.

Application filed February 3, 1900. Serial No. 3,852. (No model.)

To all whom it. may concern:

Be it known that I, AUGUST FREDRIOKSQN, a citizen of the United States, residing at Meridian, in the county of Lauderdale and State of Mississippi, (whose post-office address is Meridian, Mississippi,) have invented certain new and useful Improvements in Oil-Cake- Sacking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for packing cakes in bags or sacks, and particularly for packing oil-cakes which have been compressed by hydraulic or other pressure.

It consists in a machine having a longitudin-ally moving screw carrying plunger=heads, a threaded pulley adapted to reciprocate the said screw, and means for automatically stopping the revolution of the said pulley and nut when the cake has been placed in a sack or bag.

It also consists in a machine of this character having loading-chambers upon each side of the sleeve-nut and pulley, the said loading-chambers being provided with roller bottoms and having movable partitions for admitting the cake which is to be placed in the sack to the said chamber.

It also consists in certain other combina tions and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of amachine constructed in accordance with my invention. Fig. 2 represents a top plan view of the same. Fig. 3 is a vertical transverse cross-section through one of the loading or charging chambers looking toward the end of the machine. Fig. 4 is a detail view of the belt-shifting device, and Fig. 5 is a transverse cross-section through the same.

1 in the drawings represents a frame, 2 a reciprocating screw mounted therein, and 3 a pulley witha screw-threaded hub engaging the same. The frame 1 is formed with inner brackets 5 5 and outer end brackets 6 6, there being preferably a set of these brackets at each end of the machine. The brackets 5 are provided with inwardly-extending sleeves 7 7,

forming a bearing for loose pulleys 8 8 and the reciprocating screw 2. The sleeves 7 are formed with bearings upon their outer surfaces to loosely support the loose pulleysS 8. The inner surfaces of the said sleeves 7 7 are provided with apertures sufficiently large to permit the screw 2 to slide through them. The inner ends of the sleeves 7 7 are spaced far enough apart to accommodate the hub of the pulley 3 between them. The said sleeves 7 7, however,limit the movement of thethreaded pulley so that it cannot move longitudinally with respect to the screw-rod 2 and so that when the said pulley is rotated its internal threads 9 will engage the threads of the screw-rod 2 and move the rod longitudinally one way or the other, according to the direction in which the threaded pulley is rotated. The screw-rod 2 carries at'its ends platen or plunger heads, as 10 10. These platens are rigidly secured to the ends of the screw-rods and engage the inner faces of loading or charging chambers 11 11 upon each end of the ma chine. Two belts are preferably employed in connection with this machine and normally run upon the loose pulleys 8 8. One belt runs.

in one direction, while the other travels in an opposite direction. Then it is desired to move the screw-rod in one direction, a belt is shifted to the rim 4 of the pulley 3. When it is desired to move the screw-rod in the opposite direction, the other belt isfshifted from its loose pulley to the pulley 3 after the cake being operated upon has been deposited in its sack or bag. 'In carrying. out this operation of my invention I preferably mount a guidepiece, as 12, upon the frame, securing its ends to the brackets 5 5. This guide-piece is preferably formed with an upper dovetail groove, as 12, in which moves a dovetail block or slide 14, carrying belt-en gaging loops or shifters 15 15', one of the shifters engaging each belt and being sufficiently far apart to place each of the belts simultaneously upon the loose pulleys 8 8. The guide-piece 12 is also provided with a groove 16 upon its under surface, which receives a shifting bar, as 17. This shifting bar 17 is securedto'th'e'dovetail block 14c by means of a pin 18, which extends through a slot 19, formed in the guidepiece 12. Thus by moving the shifting bar 17 the bolt-shifters 15 15 are correspondingly actuated. The bar 17 is provided at its ends with depending bent portions, as 20 20, which extend downwardly a suflicient distance to be in the path of the platens 1O 10. By reference to the drawings it will be seen that when-one of the'platens approaches the inner end of its stroke it will strike one of the depending portions 20 of the shifting bar 17 and force the same inwardly. This will operate to automatically move the belt upon the loose pulleys and stop the operation of the threaded pulley 3. WVhen the other platen moves inwardly, the operation will be similar to the one just described, but in opposite direction. WVhen it is desired to start the movement of the'reciprocating screw-rod 2, it is necessary to move the shifters 1'5 15 by hand, so as to bring one or the other of the belts upon the pulley 4;.

The construction of the charging-chambers 11 also forms an improved part of the present invention. These chambers are formed between the brackets 5 and 6 at each end of the machine and are provided with approximately-vertical backs, as 21, while the bottomsofthese chambers are formed by mean s of a series of movable rollers 22 22. These rollers 22 22 preferably extend the full length of the charging-chambers 11 longitudinally thereof, being journaled at their ends in the brackets 5 and 6. The roller-floor thus formed is made of suflicient width to project sufficiently forward to one side of the platens 10 to permit a charge of cakes necessary to fill the bag to be placed on the front part of the floor before it is moved in front of the plungers. The brackets 6 project forward the full width of the extended roller-floor, as seen in Fig. 3 of the drawings, and to the height of the charge of cakes, thus making it possible to arrange the cakes smoothly at the ends by piling them against said brackets, and thus to produce a neat rectangular-package. In orderto prevent the cakes from being placed too far in upon the said floors and from traveling rearwardly on the rollers too soon, I employ a vertical sliding partition, as 23, which moves in ways or grooves 24 24, formed in extensions 25 25 of the brackets 5 and 6. If desired, the upper ends of these extensions 25 25 may be connected by a cross-piece, as 26, in which may be mounted a pulley 27. By placing a rope, as 28, over the pulley 27 and connectingone end of it with the slide 23 the said slide may be easily raised and lowered, as desired, by the persons operating the machine. In practice the machine is so set as to place the roller-floors 22 22 upon a slight incline to the rear, so that when a charge of cakes is placed upon one of the said floors it will rest against the partition 23, and when it is desired to feed the said cake into the charging-chamber 11 and in front of the plunger 10 it is merely necessary to raise the slide 23, when the action of gravity will cause the cake to move upon the roller-floor into the said chargingchambers.

The vbrackets 6 6 are each of them provided with a telescoping guide forming an expanding nozzle or filler, as 29, to direct the cakes into the sacks or bags. These fillers 29 are formed with rigid side pieces 30 and upper and lower hinged pieces 31. The hinged pieces 31 31 are hinged to the brackets 6, and their outer ends are left free, but are preferably connected by means of springs, as 32, so as to be normally held in their collapsed positions, as seen in Fig. 1 of the drawings. It will be seen that it is an easy matter to slip the mouth of a bag or sackupon the collapsed end of one of the fillers 29 and that when the piston or plunger 10 forces a cake out of the charging-chamber into the said filler it will spread the hinged pieces 31 and be guided by the said filler into the bag or sack.

It will be apparent from the above description that my sack-filling machine is exceedingly simple in construction and that as soon as a cake is deposited in its bag by one platen the other one will engage the depending end of the shifting rod 17, so as to force it along and move the bolts to the idler-pulleys, there by stopping the operation of the machine. It will be seen that this automatic control of the mechanism works equally well from either end of the machine. It will be further noted that while one charge of cakes is being forced into its bag or sack at one end of the machine another charge of cakes may be deposited upon the roller-floor at the other end of the machine in readiness for the return move ment of the screw-rod 2, making it possible to place cakes in their sacks or bags with great rapidity. It will be further seen that the sliding partitions 23 used in connection with the roller-floors 22 make it a very simple and easy matter to admit the cakes to the charging-chambers.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for packing cakes in bags, the combination of a frame comprising vertical brackets or standards, a reciprocating screw-rod having bearings in two 'of said brackets, platens carried by the said rod and extending into chambers formed at each end of the machine, a pulley mounted upon the screw-rod outside the said chambers, bearings formed upon the standards upon each side of the said pulley, the said bearings having inner and outer bearing-surfaces, the inner ones receiving the screw-rod, and pulleys mounted upon the outer bearing-surfaces and arranged upon either side of the rod-actuating pulley, and means mounted above the said pulleys for shifting operating-belting, the said means being located between the platens so as to be alternately struck by the same upon the reciprocation of the screw-rod, substantially as described.

'2. A machine for packing cakes in bags,

comprising standards, inwardly-extending bearings on two of the said standards having inner and outer bearing-surfaces, a reciprocating screw-rod adapted to move longitudinally upon the inner bearing-surfaces, loose pulleys mounted upon the outer bearing-surfaces, an internal screw threaded pulley mounted upon the screw-rod and engaging the threads thereof, the said pulley being held against movement longitudinally with the rod by the abutting ends of the said bearings, platens carried by the ends of the reciprocating rod, a belt-shifting mechanism mounted upon the standards comprising a single rod or bar moving in a suitable bearing, depending end portions formed on the said bar and projecting between the platens upon the ends of the rod, the said bar being sufficiently short so that the platens will onlyengage the depending portions when they approach the inner extremities of their movement, and means carried by the said bar for engaging straight and cross belts upon the loose pul leys, whereby one or the other may be moved automatically upon the actuating-pulley for reciprocating the screw-rod.

3. A machine for placing cakes in bags or sacks comprising a framing formed with inner and outer brackets, a reciprocating screw, carrying plungers mounted in the inner brackets, means for reciprocating the said screw and plungers, charging chambers formed at each end of the machine adapted to inclose the said plungers, a series of rollers forming the floors of the said chambers, the said floors beingslightlyinclined,whereby upon placing a charge of cakes upon the inner face of the said floors, it will move by gravity in front of the plunger, substantially as described.

4. A machine for packing cakes into bags comprising a suitable frame, a reciprocating screw carrying plunger-heads mounted there in, means for reciprocating the said screw, one or more charging-boxes formed in the said frame having floors formed of a series of rollers, a sliding partition forming one side of each of the said'charging-chambers, whereby upon placing a charge of cakes upon the said floor it will first rest against the partition and when the partition is raised the cake will move by gravity in front of the plunger, substantiallyas described.

5. A machine for packing oil-cakes in sacks comprising a suitable framing, a reciprocating screw-rod mounted therein having plungers secured thereto, one or more chargingchambers formed in the said framing pro vided with a suitable back, rollers forminga floor for the charging-chambers, a sliding partition mounted in front of each chamber, a rope and pulley for raising the said partition, and means for directing the cake from the charging-chamber into the sack or bag, substantially as described.

6. A machine for packing oil-cakes in sacks comprising a suitable framing, a reciprocat= ing screw-rod mounted therein having platens secured thereto, charging chambers formed in said frame, a roller-floor for receiving a charge of cakes, said floor projecting forwardly from the chamber, an end platoon the framing to facilitate the even piling of the cakes, and means for permitting the cakes to move into the chambers to be forced into sacks, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

AUGUST FREDRICKSON.
